Intent URL in mobile Chrome for testing multiple android package names

I'm using an intent URL to launch an app from mobile Chrome, or if the app is not installed fallback to a URL. It's described at https://developer.chrome.com/multidevice/android/intents.

Now I have encountered an app that exists with two different package names.

Is there any URL syntax or other solution that lets me try two different package names before falling back to a URL?

The preferred solution would:

1. Try to open package name A.
2. If A does not exist, try to open package name B.
3. If neither was installed, go to fallback URL in mobile Chrome.
